How Much Compensation for Damp and Mould in the UK?
Compensation amounts depend on four main factors: how long the problem was left unresolved, the severity of the health impact, the extent of damage to belongings, and whether you are in social or private rented housing.
| Severity | Typical Compensation | What it covers | Route |
|---|---|---|---|
| Minor | £250 – £1,000 | Isolated mould patch, short delay in repairs, minor inconvenience | Complaint / Ombudsman |
| Moderate | £1,000 – £5,000 | Multiple rooms affected, damaged belongings, mild health symptoms, several months of neglect | Ombudsman / Disrepair claim |
| Severe | £5,000 – £10,000+ | Long-term health damage (asthma, eczema), children affected, years of landlord inaction, damaged belongings and loss of use of rooms | Court / No-win no-fee solicitor |
| Exceptional | £10,000+ | Severe personal injury, extensive property damage, deliberate landlord obstruction, combined damages including lost earnings | County Court / High Court |
What you can claim for
A damp and mould compensation claim can cover several heads of damage:
✓ Claimable
- Damaged clothing, bedding, furniture
- Medical costs (prescriptions, GP visits)
- Loss of income if illness caused you to miss work
- General damages for distress and inconvenience
- Loss of use of rooms (rent reduction equivalent)
- Temporary accommodation costs if you had to move out
✗ Not claimable
- Mould caused by your own behaviour (e.g. no heating, drying clothes without ventilation)
- Issues you failed to report to your landlord
- Damage outside the limitation period (6 years for property, 3 years for personal injury)
- Speculative future losses without evidence
Real Case: Housing Ombudsman Orders £6,500 Compensation
Lambeth Council ordered to pay £6,500 after family left in damp for nearly six years
The Housing Ombudsman found severe maladministration after Lambeth Council left a mother and her family — including a three-year-old with severe eczema — living in a property with a leaking roof causing damp and mould in the loft, kitchen, living room, and bedroom.
Key failings included: failed repeated repair attempts; scaffolding blocking natural light for 27 months; a five-month delay responding to a safeguarding enquiry from the child’s school; and persistent record-keeping failures meaning the landlord could not produce a tenancy agreement or inspection reports.
The Ombudsman also ordered Lambeth to apologise in person, carry out an inspection, complete all outstanding works, and review its complaints processes. Read the full Housing Ombudsman report →
The landlord’s inability to produce basic documents — tenancy agreement, inspection records — was a significant factor in the severity finding. Document everything from the start. If your landlord’s records are poor, that can work in your favour.
Is My Landlord Responsible for Damp and Mould?
Under the Landlord and Tenant Act 1985 and the Homes (Fitness for Human Habitation) Act 2018, landlords must keep the structure of a property in repair and ensure it remains fit for human habitation throughout the tenancy.
Landlords are responsible where damp and mould are caused by:
- Leaking or defective roofs (as in the Lambeth case above)
- Rising damp due to a failed or absent damp-proof course
- Penetrating damp from defective external walls, pointing, or gutters
- Leaking pipes, plumbing, or drainage issues
- Poor ventilation that is a design or structural fault of the property
- Condensation caused by insufficient heating systems provided by the landlord
Landlords have historically blamed tenants for condensation mould by calling it a “lifestyle issue.” The Housing Ombudsman’s 2022 spotlight report ‘Damp and Mould: It’s Not Lifestyle’ challenged this directly. Landlords can no longer simply blame tenants for not ventilating without investigating the root cause. The burden has shifted.
When the landlord may not be responsible
If mould is genuinely caused solely by tenant behaviour — such as consistently failing to heat the property at all, blocking ventilation, or drying large amounts of laundry in a sealed room — the landlord’s liability may be reduced. However, this is not a blanket defence, and courts increasingly scrutinise such claims.
Health Effects and How They Affect Your Claim
Health damage is one of the strongest factors in increasing compensation. Medical evidence — GP letters, prescriptions, hospital referrals — directly strengthens a personal injury element of your claim.
| Health symptom | Short-term (weeks) | Medium-term (months) | Long-term (years) |
|---|---|---|---|
| Respiratory problems (coughing, wheezing) | Mild onset | Worsening | Chronic / asthma |
| Allergic reactions | Mild | Sensitisation builds | Severe, ongoing |
| Fatigue and headaches | Intermittent | Persistent | Debilitating |
| Skin conditions (eczema, rashes) | May appear | Worsening | Chronic |
| Cognitive effects (brain fog, memory) | Unlikely | Early signs | Significant impact |
| Mood disorders (anxiety, depression) | Unlikely | May emerge | Documented cases |
Claims involving children, elderly residents, or people with pre-existing respiratory conditions carry greater weight. In the Lambeth case, the child’s eczema was explicitly cited. If a child or vulnerable person in your household has been affected, document it carefully with medical records.
How to Make a Damp and Mould Claim: Step by Step
Report the issue in writing
Email or letter your landlord describing the damp or mould, its location, and when you first noticed it. Attach dated photographs. This creates a formal paper trail and triggers their legal duty to respond.
💡 Tip: Use “recorded delivery” for letters or request a read receipt for emails. Keep all replies.
Give a reasonable time to respond
Landlords typically have 14–28 days to respond and begin works for non-emergency repairs. Awaab’s Law (social housing) now requires a response within 14 days and emergency action within 24 hours where health is at immediate risk.
Escalate to Environmental Health
If your landlord ignores you, contact the Environmental Health department at your local council. They can inspect the property and issue an Improvement Notice or Hazard Awareness Notice, which puts legal pressure on your landlord and provides you with official documentation.
💡 Tip: An Environmental Health report is powerful evidence in any subsequent claim.
Social housing? Use the Housing Ombudsman
If you are in a council or housing association property, escalate your formal complaint to the Housing Ombudsman Service. It’s free, has teeth, and can order compensation and repairs. You must exhaust the landlord’s internal complaints process first.
Private tenant? Consider a housing disrepair claim
Contact a solicitor who specialises in housing disrepair. Many operate on a no-win, no-fee basis. They will send a Letter of Claim to your landlord requiring a response within 21 days, then issue proceedings if the landlord fails to act.
💡 Tip: Check if you qualify for legal aid first — if your household income is low, you may be entitled to free legal representation.
Instruct a professional damp survey
A CSRT-qualified surveyor’s report identifying the cause of damp — structural, not lifestyle — is one of the most effective pieces of evidence in a claim. It rebuts the landlord’s “condensation lifestyle” defence and substantiates the disrepair.

Awaab’s Law and New UK Damp and Mould Rules (2024)
Awaab Ishak was a two-year-old boy who died in December 2020 from a respiratory condition caused by extensive black mould in his social housing flat in Rochdale. The coroner ruled his death was caused by prolonged exposure to mould. His landlord, Rochdale Boroughwide Housing, had repeatedly dismissed the family’s complaints.
As a direct response, Awaab’s Law was introduced through the Social Housing (Regulation) Act 2023 and came into force in 2024. It requires social landlords to:
Awaab’s Law currently applies only to social housing. However, the Renters’ Rights Bill (progressing through Parliament in 2025) is expected to extend similar protections to private tenants. The Homes (Fitness for Human Habitation) Act 2018 already applies to all rented properties.
Evidence Checklist for a Damp and Mould Claim

- All landlord replies (including silence)
- Environmental Health inspection report

Frequently Asked Questions
How much compensation can I get for damp and mould in the UK?
Compensation ranges from around £250 for minor, quickly resolved issues up to £10,000 or more for severe, long-standing cases involving health damage. The Housing Ombudsman awarded £6,500 to a family left in damp and mould for nearly six years (Lambeth Council, 2023). Private court claims can exceed this where personal injury is proven.
The key factors that increase compensation are: duration of the problem, health impact (especially on children or vulnerable residents), number of rooms affected, value of damaged belongings, and the degree of landlord negligence or delay.
Can I sue my landlord for mould?
Yes. Under the Homes (Fitness for Human Habitation) Act 2018 and the Landlord and Tenant Act 1985, landlords have a legal duty to keep rented properties in repair and free from serious health hazards. If mould is caused by a structural defect and your landlord has failed to fix it after you’ve reported it in writing, you can take legal action.
You can pursue this through a housing disrepair solicitor (many work on no-win no-fee), the Housing Ombudsman (social housing), or directly through the small claims court for lower-value cases.
Can I get compensation from my landlord for mould without going to court?
Yes, in many cases. Most housing disrepair claims settle before reaching court once a formal Letter of Claim is sent by a solicitor. For social housing, the Housing Ombudsman can order compensation without court proceedings. Environmental Health notices also often prompt landlords to repair quickly and sometimes make goodwill payments to avoid formal action.
What is the Housing Ombudsman compensation for damp and mould?
The Housing Ombudsman can order social landlords to pay compensation alongside completing repairs and improving their processes. In its most serious cases — rated “severe maladministration” — awards can reach £6,500 or more. The Ombudsman can also require a personal apology, an independent inspection, and a review of internal policies.
You must first exhaust your landlord’s internal complaints process (usually two stages) before the Ombudsman will accept your case. The service is free to use and its decisions are legally binding on landlords.
What is a damp compensation calculator?
There is no official “damp compensation calculator” — compensation is assessed case by case. However, the main variables are: duration of the problem (longer = more), health impact (medical evidence is key), number of rooms affected, and the total value of damaged belongings. A housing disrepair solicitor can give you a realistic valuation of your claim during a free initial consultation.
What is the new law on damp and mould in UK rental properties?
Two key pieces of legislation apply:
Homes (Fitness for Human Habitation) Act 2018 — applies to all rented properties and requires landlords to keep homes free from serious health hazards, including damp and mould, throughout the tenancy. Tenants can take direct legal action in court if landlords fail to comply.
Awaab’s Law (Social Housing (Regulation) Act 2023) — applies to social housing and requires landlords to investigate damp and mould within 14 days, begin emergency repairs within 24 hours, and complete repairs within prescribed timeframes. It came into force in stages from 2024.
How do I complain about damp and mould in a council house?
For a council house: (1) Report the damp or mould to your council’s housing repairs team in writing. (2) Follow up through the council’s formal complaints procedure if repairs are not made. (3) If you reach the end of the complaints process without resolution, escalate to the Housing Ombudsman Service at housing-ombudsman.org.uk. You can also contact Environmental Health at the same council for an independent inspection.
Can I withhold rent because of damp and mould?
UK law does not give tenants a straightforward right to withhold rent. Doing so without proper legal advice risks eviction and could harm your claim. A safer approach is to pay rent into a separate account and seek legal advice — a solicitor can advise on whether a rent reduction order through the court is appropriate in your specific circumstances.
